Book of Exalted Deeds
James Wyatt, Christopher Perkins, Darrin Drader
On a successful critical hit against an evil creature, this weapon discharges a Radiant Burst that deals +3d6 points of damage to the target and blinds it for 1 round. A successful DC 14 Fortitude save negates the blindness. Bows, crossbows, and slings so crafted confer the heavenly burst power upon their ammunition.
